This blog provides a clear, side-by-side comparison of CAPEX vs OPEX solar, focusing on cost, ROI, and long-term savings.

Understanding the Two Solar Models

What Is CAPEX Solar?

CAPEX (Capital Expenditure) solar is the traditional model where the consumer:

• Pays upfront for the solar plant

• Owns the system

• Uses generated power for their operations

What Is OPEX Solar?

OPEX (Operational Expenditure) solar allows businesses to:

• Install solar with zero upfront investment

• Buy solar power at a fixed lower tariff

• Avoid ownership and maintenance

CAPEX Solar Model Explained (Ownership Model)

How CAPEX Solar Works

• One-time investment by the business

• Solar plant installed on rooftop or land

• Business consumes solar power directly

• Excess energy exported (net metering, if applicable)

CAPEX Solar Costs in India

• Typical cost: ₹40,000–₹55,000 per kW

• Large commercial systems have lower per-kW costs

ROI & Savings

OPEX Solar Model Explained (Zero-CAPEX Model)

How OPEX Solar Works
